IEEE_DIVIDE_BY_ZERO

hi,

I am trying to do a simulation of fish larvae using the vertical migration option. My release depth is 1m. and my vertical matrix is as follows:

3
2
10 50
1728000 1728000 2073600
100 0 100
0 100 0

when execute the cms run, I get an error saying " Depth in release file is greater than depths in vert_matrix file
Note: The following floating-point exceptions are signalling: IEEE_DIVIDE_BY_ZERO"

But, the depths in my release file are not greater than the depths in the vert_matrix file. Why do I get this error? What should I do?

Here's what I got:
~/cms/connectivity-modeling-system-master/cms-master/expt $ ./cms 280915
ibiotimestep 300

File name : traj_file_1.nc
Total number release locations : 54 (1 to 54)
Total number of particles released : 5400
Total number of time steps : 18757
Total number of time steps in output file: 1561
Depth in release file is greater than depths in vert_matrix file
Note: The following floating-point exceptions are signalling: IEEE_DIVIDE_BY_ZERO

Thanks

The issue is solved by having greater depths in the vertical matrix file.
Here's the new vertical matrix file that I made and it works!
